ozomi'ron.

To all whom it may concern:

Be it known that I, Louis GOLDBERG, a citizen of the United States ofAmerica, and a resident of Indianapolis, county of Marion7 State ofIndiana, have invented certain new and useful Improvements in @senators7of which the following is a speciiication.

The main objects of this invention are to provide an improved forni ofozonator; to provide a simple'and eiiicient construction of centralterminal; to provide an improved and inexpensive form of conductorterminal with positive contacting mechanism disposed upon a substantialdielectric; and to pro vide an improved form of construction in whichthe Working parts are readily removable from the casing, givingaccess-to the air passages.r

An illustrative embodiment of this inven-v tion is shown in theaccompanying drawings, in which I Y Figure 1 is fa longitudinal sectionof an ozonator assembled, the central terminal being in elevation. Fig.2 is the dielectric tube, with the conductor and terminal contact springin place. Figr is a sectional View on the line A-A of Fig. 1. Figrd islasec' tional view on the line B-B of Fig. 1.

In the form shown, acasing 1 forms a housing for the Working oit' themechanism and a conined space through which air isy passed in theprocess of producing ozone.) Loosely fitting the internal Wall of thecasing is a tube 2 of dielectric material. round on the central portionof ythe external surface of the dielectric tube is an insulatedconductor 3. A metallic band l encircles the tube and has its ends bentoutward to provide lugs which are connected by a screw and serve as aycombined clamp and terminal post 5 to which is secured the adjacent endof the conductor 3. One end of the casing 1 is provided with i spacingblock G which is provided with air distributing passages 7. The spacingblock 6 is provided with a shoulder 8, which contacts with one end ofthe dielectric tube?. The external surface ofthe spacing block 5 isturned to lit the internal surface of the dielectric tube 2.

, An inlet for air to the apparatus is provided by a tubular projection9 which is. fitted into thel center of the lower end of the casing 1. Asupport for a central or inner i electrical terminal is provided by ametallic sleeve 10, which occupies the center oi' the spacing block 6.Screw-threaded luto the Specification of Letters Patent.

sleeve 10 is an inner terminal rod 11 which is' provided at its upperend With a head 12 and `a baffle plate 13. A number of longitudinalslots 14 are cut radially in the cent-ral rod 11., Fitted into each slotis a fiat metal strip which is secured in the slot by prickpunching therod close to the slot after the strip 15 has been inserted in the slot.The external ed e of thestrip 15 is provided with serrations orming alarge number of discharge points from the inner termi-nal. Electricalcontact, with the central terminal is formed by a metal connector 16.which is secured to the metallic sleeve 10 by a machine screW 17. Theconnector 16 isalso secured to a terminal post 18 which projectsthroughl the casing 1. Betweenthe connector 16 and the spacing block Gis placed a Wire screen 19 which completel covers all of the airVdistributing passages The electrical contact With the conductor 3 ismade by Way of the metallic strip f1 with a resilient metal strip 20,which is so securedto the inner surface of the casing 1 as to yieldinglybear toward the strip 4f. The usual terminalpost 21 is located exteriorto the casing and is in metallic con'- t-act with the spring contactstrip 20 through the machine screw 22. Insulated thumb nuts '23 aresecured to the upper Aend of the cas: ing lon threaded pins 24. Thesethumb nuts may be used to secure a collector or cap to the delivery endof the casing.

In operation, the terminal posts 18 and 21 are connected to thesecondary of a transformer or to any source of electromoiive force of.the required potential and frequency.

Then the terminals are so connected, an eiiluve or silent discharge Willtake place between the inner and outer conductors.

When the apparatus is in operation, a current of air is forced into theinlet 9 Where it enters a cavity communicating with the air distributingpassages 7. The air passages aresymmetrically distributed in closeproximity to the dialectric tube. As the 'process progresses, theozonized air is forced out ofthe cent-ral rod 1l from the sleeve 1.0,whereupon it can be withdrawn through the open top of the casing. Thedielectric tube with its conductor and ucontact member m'ay be slippedott from the block 6 and the block 6 may be disconnected from the casingby merely nnscrewing thc binding post 18 from the screw shank by whichit is connected to the contact member 16.

Although but one specific embodiment of this invention is herein shownand described, it will be understood that'numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention, as defined by the following I claims.

1. An ozonator, comprising a casing having a contracted inlet opening atone end, a block seated over said opening and having therethroughaseries of distributed air pas sages communicating with said inletopening, a dielectric tube mounted in `said 'casingv and having itsinterior in communication with said distributed air passages, so as toprovide a continuation thereof along said casing, an outer electrodedisposed around the outside of said dielectric tube, an inner electrodecarried by said block, being located concentrically within said tube andcomprising la metallic body shaped to provide a multiplicity ofdistributed projections uniformly spaced with respect, to said outerelectrodes, and means for connecting said electrodes to a suitablesource of electroinotive force.

2. An ozonator comprising a casing havim@T a contracted inlet. openingat one end, a block seatedA over said opening and having theretlnough a.series of distributed air passages communicating with said inletlopening, a dielectric tube mounted in said casing and having itsinterior in communication with said distributed air passages, so as toprovide a continuation thereof along said ing a metallic body shaped toprovide a multiplicity oli' distributed projections uniformly spacedwith respect to said outer electrode, and 'means for connecting saidelectrodes to a suitable source of electromotive force, and coniprisinga binding post A having a shank extending loosely through said casing'aud sccaued to said block and thereby serving' to hold said block inposition in said easing.

3. An ozouator, coniprisii'ig a casing hav- 60 ing a contracted inlet.opening at one end, a blocl-I litting within said casing adjacent tosaid inletLand having therethrough a plurality ol' distributed airpassages communicating with said inlet, a cylindrical shoulder formed onsaid bloch, a tubular dielcet ric tit;- ting said shoulder and adaptedto be supported thereby in said casing, an outer electrode disposedaround said dielectric tube, an inner electrode having screw-threadedconnec- 7o tion with said block and located concentrically within saidtube, said electrodes being formed to provide opposed projectionsdistributed throughout the contiguous areas of said electrodes, theprojections on one of Said electrodes bcinsr uniformly spaced away tromthose on tic other, the end of said casing which is opposite saidcontracted air inlet'. laing arranged to permit said block, dielectrictube and clcctrodes to ,be \\'ithdra\\'u thercthrough, and means forconnecting said electrodes with a suitable sourct` ot' eltwtroufiotivetorce.
